The whole product

Nine screens, and what each one is for.

Every image on this page is a capture of the running desktop application on the current build. Nothing here is a mockup, a concept, or a screen we intend to build later.

01 · Timeline

The day you actually had.

The hero screen. Your real day laid out on a real time axis, one block per stretch of work, with the document or subject line that makes it recognisable later. Scroll back to any past day and it is all still there.

Click a block to see its document and time; select several to tidy or delete
Add time by hand for the phone call and the drive that your computer never saw
Split a block when one stretch was really two jobs
Away time is written as away time, never billed as work
Search across everything you have ever recorded, from the top bar

Project Timebook timeline for Sunday July 19 showing 7 hours 41 minutes tracked across the day

02 · Insights

What your time actually did.

The summary a timesheet never gives you. How much you tracked, how many apps you touched, how many times you got pulled away, and how long your longest uninterrupted stretch really was.

Time per application for the day, largest first
Your deepest stretch of focus, named
App switch count, which is usually the uncomfortable number
Nothing to file; every minute is already counted

Insights screen showing 7h 41m tracked, 7 apps used, 16 app switches, 45m longest focus, and a bar chart of time per app

03 · Reports

The number you put on the invoice.

Pick a range, group it the way you bill, round it the way you bill, and take it out as a file. The per-entry CSV is the integration: anything that reads a spreadsheet can read your hours.

Today, yesterday, last 7, last 30, this month, or any custom range
Group by app or day
Round up to 5, 6, 10, 15 or 30 minutes, or keep exact time
Export this report, every entry, or everything you have ever recorded

Reports screen showing 25h 01m across the last 7 days grouped by app with percentages and export buttons

04 · Client Brief

The whole update, written from what you actually did.

The one feature that talks to the internet, and only when you press the button. Pick a period and it reads the apps and documents it recorded for you, then writes a detailed, client-ready brief of the work, using your own OpenAI API key so the request goes from your machine straight to OpenAI and never through us. You read the exact summary it will send before anything leaves.

Off until you ask for it, every single time
Optional, and blank unless you add your own API key
Built from your real recorded work: the apps and documents, with their time
Shows you the exact summary first, so there is no guessing
No projects to set up and nothing to file first

Client Brief screen showing the previewed per-app document summary that would be sent and the draft it produces

05 · Calendar

Your meetings, without handing over your password.

Meetings show up on the timeline next to the work. Project Timebook does not ask for your Google or Microsoft login, because it does not need it. It reads the calendar copy your desktop already keeps on this disk, or an .ics file you point it at.

Uses the calendars your desktop has already synced locally
Or imports a plain .ics file, no account involved
"No calendar at all" is a real answer and it is one click
It asks you on first run, it never just starts reading

Calendar screen showing the local calendar source choice and imported meetings

06 · Privacy

The rules, enforced before anything is written.

One table drives all of it. Set an app to Full, App only, or Never, and the rule is applied at the moment of capture. A Never app produces no row, no title, and no app name. There is nothing stored to hide, redact, or leak.

Track everything and name your exclusions, or run a strict allowlist
Rules are matched on the executable, not the window title
Delete one entry, a whole day, or erase everything
A delete genuinely removes it, it does not just hide it

Privacy screen showing per-application recording rules set to Full, App only or Never

07 · Appearance

Dark, light, or exactly your colours.

Follow the system, pick dark or light outright, or set your own background, text and accent. It is your desktop and you are going to be looking at it all day.

Dark, light, or follow the system
Custom background, text and accent colours
Applies to every screen instantly

Appearance screen in light theme showing theme mode and custom colour controls

08 · Settings

The knobs that matter, and no others.

Idle threshold, start with your session, calendar source, and your data controls. Project Timebook does not have a settings screen with four hundred switches, because it does not need one.

Set how long away counts as away
Start recording quietly when you log in
Export everything you have, whenever you want
Erase everything, permanently, from the same screen
